We've covered how long a reusable, rechargeable device lasts over its whole working life in a separate guide — this is specifically about a single disposable: what its advertised puff count actually means, and why two people can get very different mileage from the exact same device.
Manufacturers estimate puff count based on an average draw length and frequency under controlled testing conditions — it's a rough guide meant for comparison between products, not a guarantee of exactly how many draws any individual will actually get, since real usage varies enormously from person to person.
Longer, harder draws and more frequent use both burn through e-liquid and battery meaningfully faster than the testing conditions used to generate the advertised number. Someone taking short, spaced-out draws will consistently outlast someone chain-drawing the identical device.
Manufacturers try to size the battery and e-liquid volume to run out around the same time, but usage pattern can make either one the actual limiting factor first — heavy, frequent use tends to drain the battery faster relative to liquid, while very light, spaced-out use sometimes runs the liquid dry before the battery is meaningfully depleted.
In practice, most disposables last somewhere between a few days and one to two weeks for a moderate daily user, considerably less for someone vaping heavily and frequently throughout the day. The advertised puff count is worth treating as a rough ceiling rather than an expected average.
Longer or more frequent draws than the manufacturer's testing conditions assumed is the most common reason — the advertised number reflects a specific, moderate usage pattern that doesn't match everyone's actual habits.
Cold temperatures can temporarily reduce battery performance, which may make a device feel like it's underperforming in cold conditions even though the underlying capacity hasn't actually changed.
Slower, shorter, more spaced-out draws are the main lever within your control — beyond that, the device's total capacity is fixed from the point of manufacture.
